fLike letters of reference in all the figures indicate the same parts.

My invention consists of a perforated leaden form, and covering made of lamp wick or other similar material, wound around it and stitched thereto, the form having or more continuous or endless rows of perforations for that purpose, I

A is my improved gasket, shown in Figs. 1 and 2; and B, as shownin Figs. 3 and 4, is a perforated leaden form, which has one or more rows of perforations, continued throughout its whole entent of surface. Lamp-wick or other similar material is Wound around the form and stitched through the perforations, to form a pliable covering for the form. Before the gasket is used it should be coated with some suitable material for filling the interstices of the wrapper. The gasket possesses great flexibility, so as to be readily brought into a immediate contact with the surfaces of the joints and, also, if not of the exact form of the hole it surrounds, it is readily brought into the corresponding form.by springing it edgewise.

I claimas my invention- A gasket for hand-holes, man-holes, and

cylinder-heads, consisting of the perforated leaden form B, and lamp-wick or other similar material wound around it and stitched thereto, substantially as set forth.
